Question

2. Nonlinear regression Fit the above data with the following curve-fit equation: y \approx b_1 (\exp(b_2x) + \exp(b_3x)) Define a function of the sum of squared residuals (fSSR) as a function of the regression coefficients (b's). Minimize the fSSR function and determine the regression coefficients. Make a guess; what would be the built-in math function to generate the original data? Plot the function in the existing figure with a smooth dashed line. Calculate the coefficient of determination and the standard error of estimate.

Step 1

Assuming you have the x and y data stored in separate vectors, you can import them into MATLAB using the following code: ```matlab x = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]; y = [0.5, 1.7, 3.4, 4.5, 6.1, 7.8, 9.2, 10.5, 12.3, 13.9]; ``` Show more…
